The word “waste” may summon thoughts of unbearable stench, diseases, health hazards, and social issues, but in fact behind all of these negative aspects of waste lies some hidden potentials.  Waste may be processed into fertilizers, or burned as a source of fuel to power electricity.  One example of this power generation scheme is the Bantar Gebang Final Disposal Point, in Bekasi, West Java.

Bantar Gebang receives a daily amount of 6000 metric tons of waste, of which mostly consists of organic matters.  These types of waste may then be used to generate electricity by applying pyrolysis and GALFAD (GAsification, LandFill gas and Anaerobic Digestion) processes.  Pyrolysis itself is a smokeless burning process, which leaves zero emissions to the environment.

This is a relatively simple process, beginning with the separation of methane gas from water in a screening filter, due to the large amount of water contained in waste.  These screened methane gas are then put through a drying process in order to burn more effectively.

After the drying process, the gas is then fueled to a power generator, also known as a gas engine.  Inside this engine, the gas is ignited to power electric generator, producing electricity.

Implementation of these technologies is carried out by PT Godang Tua Jaya as the operator of Bantar Gebang Final Disposal Point, in conjunction with PT Navigat Organic Energy Indonesia, Sindicatum Capital Carbon, and Organic International Limited.  PT Navigat Organic has a vast experience in the waste-based power generation, having operated the Sulung Final Disposal Point in Denpasar, Bali.

To produce a continued supply of electricity, Bantar Gebang would require a steady and continued supply of electricity.  This form of power generation is expected to reduce the negative impacts of waste while at the same time benefiting the local communities.
